• 【Upgraded Functionality & Adjustable Flow Rate】: Adjusting the pumping rate improves filtration efficiency, preventing issues like filtrate splashing and sample loss due to inappropriate pumping speeds, reducing sources of error in experiments, and ensuring accurate results.
• 【High Vacuum & High Flow Rate】: Employing a high-cost, high-quality dual-head vacuum pump with dual diaphragm pistons in series, it achieves high vacuum while ensuring a large suction flow rate, easily handling various small-scale vacuum pumping challenges in the laboratory!
• 【Multiple Protections & Active Cooling】: Using a higher-cost, high-quality power adapter with active fan cooling, it provides multiple protections against overvoltage, overcurrent, and short circuits, better protecting the motor, ensuring more reliable performance, and facilitating continuous operation!
• 【Low Noise & Pollution-Free】: The machine features multi-faceted noise reduction optimization design. The pump uses a dual-head high-efficiency vacuum structure, resulting in lower motor speed and less noise. The optimized installation structure allows for the installation of high-efficiency silencers to reduce vibration noise. Oil-free operation makes it more environmentally friendly.
• 【Small Size & Lightweight】: Adopting a compact design, its size is reduced by 10-50%. In laboratory settings, the pump can be quickly carried to the work area for rapid deployment of vacuum processes, improving work efficiency and facilitating later maintenance and upkeep!
